if Perimeter is P=2l+2w then
2w=P-2l
therefore
w=(p-2l)/2

By solving the formula P = 2l + 2w for w yields:

w = (P - 2l)/2

To solve the formula P = 2l + 2w for w means to make w the subject of the formula from P = 2l + 2w.

Since we have;

  • P = 2l + 2w

We need to subtract 2l from both sides of the equation so that we have;

  • P - 2l = 2w

We need to divide both sides by 2 so that we have;

  • w = (P - 2l)/2

Ultimately, solving the formula P = 2l + 2w for w yields; w = (P - 2l)/2
